General Safety Information

Handle Fluids Safely

When you work around fuel or other flammable material, do not smoke or work near heaters or other fire hazards.

Do not store flammable material in open containers. Store flammable fluids away from fire hazards. Do not incinerate or puncture pressurized containers.

Make sure machine is clean of dirt, grease, oil, and debris.

Do not store oily rags; they can ignite and burn spontaneously.

Keep a first aid kit and fire extinguisher handy.

Keep emergency numbers for doctors, ambulance service, hospital, and fire department near your telephone.

Check for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids.

If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source.

Avoid Heating Near Pressurized Fluid Lines

Flammablespray can be generated by heating near pressurized fluid lines, resulting in severe burns to yourself and bystanders.

Do not heat by welding, soldering, or using a torch near pressurized fluid lines.

Pressurized lines can be accidentally cut or damaged when heat goes beyond the immediate flame area.

Use Care In Handling And Servicing Batteries

Prevent Battery Explosions

Keep sparks, lighted matches, and open flame away from the top of the battery. Battery gas can explode.

Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer.

Do not charge a frozen battery; it may explode. Warm the battery to 16° C (60° F).

Warning

USE CARE AROUND HIGH-PRESSURE FLUID LINES

Escaping fluid under pressure can penetrate the skin causing serious injury.

Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines.

Tighten all line connections before applying pressure.

If any servicing or adjustments require the battery to be disconnected, or welding is required on the skid steer, disconnect the (–) negative ground cable. Failure to disconnect the battery may result in damage to the eic (electronic instrument cluster) monitoring system and other electrical components. If welding on an attachment is required, first remove the attachment from the skid steer boom attaching plate.

Warning

Starting an engine with a booster battery requires extreme care as batteries produce explosive gases. The slightest spark can cause an explosion.

Follow these safety tips:

1.Always shield your eyes when charging or workingnear a battery. Always provide good ventilation.

2.Cover the battery with a piece of carpet or other heavy material. Do not remove the battery vent caps.

3.Connect one cable to the (+) positive terminal of the weak battery. Connect the other end of the cable to the (+) positive terminal of the stronger battery.

4.Connect the second cable to the (–) negative terminal of the stronger battery.

5.Connect the remaining (–) negative cable end to the engine block or starter ground terminal.

6.Reverse this procedure when disconnecting the booster.
